' To all whom it may coneM:

Be it known that I, MoRRrsHoWE, a citizen of the United States, residing at Duluth,

in the county of St-{Louis and State of Min nesota, have invented certain new and useful Improvements 1n Suct1on Brackets, of which thefollowing is aspecification, reference beinghad therein to theaccompanying draw-' (mgr f This invention relates to portable supports of the cylinder to which it is securely fastor brackets, and has special reference to such a bracket designed to be suspendedin positionagainst a somewhat smooth surface by suction.

The object of the present invention to provide such a device more efiicient and-practic'al than heretofore known, and one that is capable ofbeing made more securefrom' time to time without altering its position.- Another object is to provi'desuch a device,

simple of release, and witho ut injury to same.

Other objects and advantages of the invention will appear in the further description.

Referring now to the accompanying drawing, forming part of this application, in,

which like reference characters indicate like parts:

Figure 1 is a central vertical section through one of the brackets as it would .appear attached to a'wall; and

, Figure 2is a fragmentalsideelevation of the light suspending band.

1 represents a sheet metal cylinder mounted within .a substantially frustro-conically shaped body portion 2, the base of which is considerably larger in diameter than the cylinder'and thetop fitting same snugly. A convex cap 3 covers the end of the cylinder and is snugly attached to the end thereof forming a continuation of the upper or outer end of the cone 2 in appearance.

The base flange-like termination 4 of the cone is somewhat flared as at 5 and sur mounted'by the rubber gasket 6. the same being somewhat enlarged about that portion into which the flare 5 of theflange 4 extends,

the rim 7 of the gasket lying against the inner face of theflange 4 and there tightly impinged by the expandible band 8, the opposite ends of which have lugs 9 formed thereupon with internally screw-threaded holes therein into which the bolt 10 is screwmend to the inner Wall of the body portion v2 and the oppositeend overlapping the end at 13 so astopermit free access of air therethreaded upon the ends, that ist'o say, right the body portion of the bracket.

Asia reinforcing or bracing element for the inner endof the cylinder 1 'I provide the dished brace 12'fwhich is fastened at one ened by soldering or in any desired manner. Th s bracing memberisperforated as shown through in order to maintain as largefla chamber as possible within 'the bracket.

On the inner end of the cylinder 1 C is formed-a chamber 14 having an axial port 15therein which is controlled by the valve f 16, and there are ports 17 leadingfrom; the chamber 14 into the cylinder 1. This valve as is obviousmay be of anydesired structure,

Within the cylinderl ismounted a piston rod- 18 carrying the piston 19 which is of the common air; pump construction, that is free to operate inwardly and function only as a suction device when drawn out wardly. 'Onthe outer end of the piston rod 18 is formed double looped portions 20 for convenient 'manipulation with two fingers. About the piston rod 18 is mounted a contractile spring 21which is attached to the pistonrod adjacent the piston 19 as at 22 and extending outwardly of the head 90. 3 of the cylinder whereit is attached as at 23, so that there is at all times a stress outwardly upon thepiston, the object being to maintain as nearly as possible a uniform suction within the bracket, such outward stress .of'the piston compensating for any insignificant leaks that might occur in the device. 7 About the outermost small end of thebody portion 2 ismounted a light supporting 199 band or ring 24, there being a concaved seat about the exterior of the body portion for installation of same. This band is pro- Vided with opposed lugs 25 carrying a cooperative thumb. screw 26 by which the 195 band may be tightened or loosened as desired about the extremity of the bracket. Opposite the termini of the band are attached thereto similar spaced lugs indicated at 27, and intermediate of which is pivotally mounted as at 28 one arcuately shaped arm 29, foldable when desired up against the body portion 2. At the tree end of this arm is pivotally mounted as at a like arm 31 carrying upon its extreme end at 82 the electric lamp 33. By this arrange ment it is apparent that the lamp may be adjusted slightly to or from the bracket and may be placed in any desired position radially about the brackets.

From the foregoing it is apparent that I have produced a suction bracket of very simple'and practical construction and one that may be attached to a smooth flat surface with considerable force or pressure resulting upon the extent to which the pumping poi: tion of the device is operated, and one that may be readily adjusted. For the purpose of convenient release o l the bracket when desired there is provided the plug 3a pivotally mounted as at 35 and controllable by the handle 36 thereupon, the same being held norm-all closed b the swin 3'? which keeps the plug 3% in the hole in the body portion 2.

Having thus described my invention, What I claim and desire to secure by Letters Patent, is:

1. A suction bracket of the class described comprising an air pump, a housing attached to the base of the pump forming a chamber communicating therewith, a resilient cushioning means about the free contacting edges of the housing, a piston Within the pump, and means whereby the piston normally tends to exhaust the chamber.

2. A, suction bracket of the class described comprising an air pump, a substantially frustroconically shaped casing surroundingthe pump forming a chamber thereabouts, resilient surface contacting means about the base of the casing, a spring actuated piston Within the pump for normally maintaining the suction of the bracket, and means for supporting a lamp upon the bracket] A suction bracketof the class described:

comprising an air pump, a substantially trustroconica-lly shaped casingsurrounding the pump forming a chamber tl'iereabouts, resilient surface contacting means about the base of the casing, a spring actuated piston Within the pump for normally maintaining the suction of the bracket, and means for adjustably supporting a lamp on the for- Ward end of the bracket.

4-, A suction bracket of the class described con'iprising an air pump, a substantially g ature. I
